Markdown Enhancement Skill

Extend or improve the Markdown parsing and rendering in kheMessage.

When to Use

• •Adding new Markdown syntax support (tables, checkboxes, etc.)
• •Fixing Markdown rendering issues
• •Improving the text editor experience
• •Adding syntax highlighting

Current Implementation

The parseMarkdown function in index.html handles Markdown rendering:

function parseMarkdown(element) {
  const input = element.textContent
  const frag = document.createDocumentFragment()
  
  const matchers = [
    {name: 'md-codeblock', re: /```[^\n]*\n[\s\S]*?\n```/y},
    {name: 'md-h1', re: /^#[ \t]+[^\n]*$/my},
    // ... more matchers
  ]
  // ...
}

Supported Syntax

Currently supported:

• •Headers (# to ######)
• •Code blocks (``` and ~~~)
• •Inline code (`)
• •Bold (text and text)
• •Italic (text and text)
• •Strikethrough (text)
• •URLs (auto-linked)

Adding New Syntax

1. •

   Add a CSS class in the <style> block:

   css

   .md-new-syntax {
     /* styling */
   }
   

2. •

   Add a regex matcher to the matchers array:

   javascript

   {name: 'md-new-syntax', re: /pattern/y}
   

3. •

   Handle special rendering in the loop if needed

Testing

• •Test with various Markdown content
• •Verify performance with large documents
• •Check that existing syntax still works
• •Test in both light and dark themes
